Answer:

B)  70.5

Step-by-step explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

<u>Class 1</u>

45 46 51 52 53 53 61 63 64 65 66 68 70 <u>70 71</u> 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71

\implies \textsf{Median}=\dfrac{70+71}{2}=70.5

How can you use distributive property to find 3/4 times 2 and 1/3
zubka84 [21]

Answer:

1 3/4

Step-by-step explanation:

You can set it up like the distrubtive property first

3/4(2+ 1/3)    Next you use the distirbutive property instead of adding inside the parenthesis and you multiply the 3/4 by 2 and then the 3/4 by 1/3

Use 2 as 2/1 in fraction problems

3/4 * 2/1        Now multiply the numerators together and the denomenators together

3 * 2 = 6          4 * 1 =4

6/4

3/4 *1/3

3 * 1 =3

4 * 3 =12

3/12

Now we have to make them both like terms (same denominator) so we can add them, we will multiply the 6/4 by 3 (Both top and bottom)

6 * 3 = 18               4 *3 =12

18/12

Now we add the fractions

3/12 +18/12 = 21/12

Reduce that and you get

21/12 = 1 9/12  or 1 3/4

Which expresion shows 18 more than 6 + 18 6 x 18 18 / 6 18 - 6
MissTica
18 more than 6 in a mathematical expression will be 18 + 6 or 6 + 18. Because we are adding 6 to 18 or 18 to 6.
